Description

CAS: 1530-32-1 | C20H20BrP | 371.26 g/mol

Ethyltriphenylphosphonium bromide acts as a reactant in the synthesis of D-amino acids from L-cysteine-derived thiazolidines, Leiodolide A through aldol reactions and Horner-Wadsworth-Emmons olefination. It is also used in the preparation of cycloalkanoindolines through diastereoselective intramolecular inimo-ene reactions. Further, it is used as a reagent in solid-state metathesis polycondensation to prepare alkyl-dipropenylthiophene monomers and Mizoroki-Heck cyclization and cascading Tsuji-Trost cyclization reactions.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
